In what’s become a long tradition, The Roots and Okayplayer have your May music festival mapped out with Philadelphia as the location.

Questlove revealed the full line-up today via Okayplayer TV and it’s headlined by Snoop D-O-double-G backed by The Roots. The rest of the line-up is just as strong as it includes Janelle Monaé, Action Bronson, A$AP Ferg, araabMUZIK, Jhené Aiko, Just Blaze, Biz Markie (on the 1s and 2s) and, of course, The Roots (again) plus a bunch of more names.

Always, the event goes down at the Festival Pier on Penn’s Landing, Philadelphia, PA. As ever Roots Picnic goes down on the offical-unofficial first day of summer which this year means Saturday, May 31st.

Tickets for the event will be available Thursday at 12pm via a presale at RootsPicnic.com. After that, tickets will be on sale for the general public starting Friday, March 7.
